How much will a seat on Starship cost?

I'm curious, how much do you think a seat on a Starship would cost? Given the technological advancements and resources required to build and operate such a vessel, would the price be in the millions, billions, or perhaps even trillions of dollars? And would the cost vary depending on the level of luxury and amenities offered on board? It's a fascinating question, and I'm eager to hear your thoughts on the potential cost of interstellar travel.
